  2. Skin effect - Wikipedia

    en.wikipedia.org/wiki/Skin_effect

    The magnetic field inside a coaxial cable can be divided into three regions, each of which will therefore contribute to the electrical inductance seen by a length of cable. [ 11 ] The inductance L cen {\displaystyle L_{\text{cen}}\,} is associated with the magnetic field in the region with radius r < a {\displaystyle r<a\,} , the region inside ...

  3. Cable theory - Wikipedia

    en.wikipedia.org/wiki/Cable_theory

    Later, cable theory with its mathematical derivatives allowed ever more sophisticated neuron models to be explored by workers such as Jack, Rall, Redman, Rinzel, Idan Segev, Tuckwell, Bell, and Iannella. More recently, cable theory has been applied to model electrical activity in bundled neurons in the white matter of the brain.

  4. Penetrant (mechanical, electrical, or structural) - Wikipedia

    en.wikipedia.org/wiki/Penetrant_(mechanical...

    Penetrants, or penetrating items, are the mechanical, electrical or structural items that pass through an opening in a wall or floor, such as pipes, electrical conduits, ducting, electrical cables and cable trays, or structural steel beams and columns. When these items pierce a wall or floor assembly, they create a space between the penetrant ...

  5. Power system protection - Wikipedia

    en.wikipedia.org/wiki/Power_system_protection

    Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults [citation needed] through the disconnection of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by isolating only the components ...

  6. Redundancy (engineering) - Wikipedia

    en.wikipedia.org/wiki/Redundancy_(engineering)

    In engineering and systems theory, redundancy is the intentional duplication of critical components or functions of a system with the goal of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing.

  7. High-voltage cable - Wikipedia

    en.wikipedia.org/wiki/High-voltage_cable

    High voltage is defined as any voltage over 1000 volts. [3] Those of 2 to 33 kV are usually called medium voltage cables, those over 50 kV high voltage cables.. Modern HV cables have a simple design consisting of a few parts: the conductor, the conductor shield, the insulation, the insulation shield, the metallic shield, and the jacket.

  8. Umbilical cable - Wikipedia

    en.wikipedia.org/wiki/Umbilical_cable

    The umbilical cable is an armored cable that contains a group of electrical conductors and fiber optics that carry electric power, video, and data signals between the operator and the TMS. Where used, the TMS relays the signals and power for the ROV down the tether cable. Once at the ROV, the power is distributed between the electrical components.

  9. Power cable - Wikipedia

    en.wikipedia.org/wiki/Power_cable

    A power cable is an electrical cable, an assembly of one or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power . Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed.
